249: Ocean Acidification (radio)worldoceanobservatory.org | 06 Dec 2013
The most serious, debilitating circumstance affecting the ocean today may be acidification, the changing pH or acid balance in the water column with devastating impacts on the marine food chain, species migration and reproduction. In this episode of World Ocean Radio, host Peter Neill will report on the recently-released 20 Facts About Ocean Acidification.
Rising ocean acidification leads to anxious fishWorld Fishing | 05 Dec 2013
New research combining marine physiology, neuroscience, pharmacology, and behavioural psychology has revealed a surprising outcome from increased levels of carbon dioxide in the oceans - anxious fish.
Arctic study shows key marine food web species at risk from increasing CO2EurekAlert | 02 Dec 2013
(University of Exeter) A research expedition to the Arctic, as part of the Catlin Arctic Survey, has revealed that tiny crustaceans, known as copepods, that live just beneath the ocean surface are likely to battle for survival if ocean acidity continues to rise. The study found that copepods that move large distances, migrating vertically across a wide range of pH conditions, have a better chance of surviving.
Ocean acidity is increasing at an unprecedented rateUNESCO | 29 Nov 2013
The unprecedented rate of ocean acidification is one of the most alarming phenomena generated by climate change and the only way to mitigate the dangers it represents consists in reducing CO2 emissions significantly.
Ocean acidification may increase by 170 per cent this centurystakeholderforum.org | 22 Nov 2013
Marine scientists launched a major new report on ocean acidification this week at COP 19 in Warsaw. The summary for policymakers concluded that if emissions continue on the current trajectory, the acidity of the worlds oceans may increase by around 170 per cent by the end of the century, bringing significant economic losses. People who rely on the oceans ecosystem services – often in developing countries – are especially vulnerable.
Science Weekly podcast: Dr Michael Sweet on why corals catch coldsGuardian Unlimited | 18 Nov 2013
In this week's podcast Alok Jha meets marine biologist Dr Michael Sweet, lead researcher in the Coral Health and Disease Laboratory at Derby University, UK. In the week when climate talks took place in Poland and scientists sounded serious warnings about sea acidification, Dr Sweet discussed the importance of coral reefs to marine ecology and why coral is under attack not just from acidification but also from pathogens in the coral triggered by rising sea temperatures.
Ocean acidification: Hard to digestEurekAlert | 15 Nov 2013
(Helmholtz Centre for Ocean Research Kiel (GEOMAR)) Ocean acidification impairs digestion in marine organisms, according to a new study published in the journal Nature Climate Change. Researchers from Sweden and Germany have studied the larval stage of green sea urchins Strongylocentrotus droebachiensis. The results show that the animals have problems digesting food in acidified water.
Emissions boost oceans 'acid trip'BBC | 14 Nov 2013
Human emissions of carbon dioxide are increasing the levels of acidity in the oceans at rates not seen for millions of years.
FAQs about ocean acidification : OCB-OAWoods Hole Oceanographic Institution | 13 Nov 2013
The U.S. Ocean Carbon and Biogeochemistry (OCB) program, with support from the UK Ocean Acidification Research Programme (UKOA), has updated and expanded a list of frequently asked questions (FAQs) developed in 2010 by OCB, the European Project on Ocean Acidification (EPOCA), and UKOA. The FAQ is a concise, readable summary of the state of ocean acidification knowledge.
Expert assessment: Ocean acidification may increase 170 percent this centuryEurekAlert | 13 Nov 2013
(International Council for Science) In a major new international report, experts conclude that the acidity of the world's ocean may increase by around 170 percent by the end of the century bringing significant economic losses. People who rely on the ocean's ecosystem services -- often in developing countries -- are especially vulnerable.

Irukandji threat to southern watersEurekAlert | 29 Oct 2013
Researchers from Griffith University's Australian Rivers Institute have conducted a series of climate change simulation experiments to investigate whether the dangerous tropical jellyfish, the Irukandji, is likely to establish breeding populations in the South East. It was found that while higher sea temperatures could provide an opportunity for adult Irukandji to expand their range south, increasing ocean acidification may inhibit the development of juveniles.
XPRIZE dives into Earth's final frontier - our oceans and their future healthGuardian Unlimited | 22 Oct 2013
The XPRIZE Foundation, once known for competitions for spaceflight innovation, has turned its focus to the seas, launching a series of new prizes for ocean health over the next seven years. The Ocean Initiative represents the biggest XPRIZE commitment to date, reinforcing earlier competitions for devices to monitor ocean acidification and clean up oil spills."The oceans are in trouble.

Ocean acidification due to carbon emissions is at highest for 300m yearsGuardian Unlimited | 03 Oct 2013
The oceans are more acidic now than they have been for at least 300m years, due to carbon dioxide emissions from burning fossil fuels, and a mass extinction of key species may already be almost inevitable as a result, leading marine scientists warned on Thursday.
